AUTOMATIC VENT.

SPECIFICATION formingpart of Letters Patent No. 460,671, dated October 6, 1891. Application filed April 1 1890. Renewed March 9, 1891. Serial No. 384,195. (No model.)

To aZZ whom it may concern:

Be it known that I, MARK ANTHONY, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Automatic Vents; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

My invention has relation to certain new and useful improvements in automatic vents for barrels containing fermented or other liquids; and it consists of the parts and details of construction as will be hereinafter more fully set forth in the drawings, and described in the specification.

The object of my invention is to provide a vent which while being automatic in its action shall be more effective in its operation, simpler in its construction, and more durable than any device of a similar nature heretofore known to me.

Referring to the drawings, forming a part of this application, in which similar letters of reference are used to denote corresponding parts throughout the entire specification and both views of the drawings, Figure 1 is a view showing my improved vent attached to a barrel, and Fig. 2 is a vertical sectional view.

The letter A is used to indicate my improved vent, which is provided with the annular collar a near its lower extremity and with the laterally-extending arms I) 12 near the top. The upper end of the vent is reduced and screw-threaded, so as to receive the cap B. Within the upper enlarged portion 0 is formed the vacuum-chamber c, which is intersected by the air-passage d, extending the entire length of the vent, so as to permit an inflow of air into the interior of the barrel, as hereinafter explained. The vacuum-chamber is also intersected below the connection of the air-passage by the airinlet passage 6. Within said chamber is placed the ball or puppet valve 0, which is adapted to seat itself so as to close the airinlet passage-e. It will be observed that between the air-inlet e and air-passage d is the separating-partition d. The lower end of the vent may be made screw threaded or otherwise, so as to securely maintain its position within the barrel. The annular collar a may be dispensed with, if so desired; but when placed upon the'ventit provides against the vent being pushed too far within the barrel, thus acting as a guard. By means of the laterally-extending arms Z) Z) the vent maybe readily inserted into the barrel.

As liquor is withdrawn from within the barrel a vacuum is formed within the chamber c, which causes the valve 0 to be raised from its seat and at the same time allow an unobstructed passage for the inflow of air through the inlet-passage 6 into the vacuumchamber 0, through the air-passage cl, and into the interior of the barreluntil the withdrawn air has been replaced. The upward and downward pressure upon the valve being then equal and the vacuum in the chamberc being destroyed, the valve again seats itself over the air-inlet passage 6, and thus ch ecks the flow of air into the chamber 0 automatically. It will be noticed that the air-inlet passage, vacuumchamber, and airpassage leading into the barrel are formed directly within the vent-standard.

I am aware that minor changes may be made in the construction of vent herein shown and described without necessitating a departure from the nature and scope of my invention.

Having thus described my invention, What I claim as new, and desire to secure protection in by Letters Patent of the United States, 1s-

A vent for barrels and the like, consisting of an upper enlarged and circular portion having an integral internal wall or web partly circular in form and uniting with the outer wall adjacent, so as to form a vacuum-chamber, an oblique inlet through the outer wall of the circular portion,said inlet connecting with the valve-chamber, a tubular stem de-' pending from the circular portion, the passage-Way in said steln connecting, with the passage formed between the internal Web and the outer Wall or easing of the enlarged portion, the latter passage in turn connecting 5 With the vaennln-ehan1ber, lateral handles projecting from the circular head, and an annular flange upon the stem, in combination with a puppet-valve adapted to close or open the vacnnm-ehmnber, substantially as set forth.

MARK ANTHONY. In presence of- N. A. ACKER, J. H. BLOOD.
